No, “our” is not a preposition. It is a possessive pronoun (or possessive determiner).
Function of “Our” as a Possessive Determiner:
- Indicates Possession or Ownership
- Our restaurant is known for its excellent service.
- We upgraded our POS system last month.
- Used Before a Noun (Modifies a noun by showing ownership)
- Our customers love the new menu.
- The success of our business depends on great service.
Why “Our” Is Not a Preposition
- Prepositions (e.g., in, on, under, about) show relationships between words.
- “Our” does not establish a relationship between a noun/pronoun and another word; instead, it indicates possession, making it a possessive determiner (or possessive pronoun).
Thus, “our” is a possessive determiner, not a preposition.
